Summary
Many patients undergoing hip or knee replacement surgery do not receive recommended blood clot prevention. This study found only 51.5% received recommended thromboprophylaxis, highlighting a gap in care for preventing venous thromboembolism.
Area of Science:
- Orthopedic Surgery
- Vascular Medicine
- Clinical Practice Guidelines
Background:
- International guidelines mandate thromboprophylaxis for elective hip or knee arthroplasty.
- Low-molecular-weight heparin or adjusted-dose warfarin are recommended for preventing blood clots.
- Adherence to these guidelines in clinical practice remains a concern.
Purpose of the Study:
- To assess the proportion of patients receiving recommended thromboprophylaxis.
- To evaluate the incidence of venous thromboembolism (VTE) post-arthroplasty.
- To identify discrepancies between guideline recommendations and actual practice.
Main Methods:
- Prospective cohort study of 396 patients undergoing hip or knee arthroplasty.
- Data collected included patient demographics, surgical details, and thromboprophylaxis use.
- Incidence of VTE within 3 months of surgery was recorded.
Main Results:
- Only 51.5% of patients received recommended thromboprophylaxis (low-molecular-weight heparin or warfarin).
- Venous thromboembolism occurred in 5.3% of patients, with events happening both during hospitalization and post-discharge.
- No significant reduction in VTE was observed in the treated group, though this was not a randomized comparison.
Conclusions:
- Thromboprophylaxis practices at the studied institutions significantly deviate from established guidelines.
- Low rates of recommended thromboprophylaxis underscore a need for further investigation into barriers.
- Strategies are required to improve adherence and optimize patient care to prevent VTE.
